Coal mining is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a "pit", and above-ground mining structures are referred to as a "pit head". In Australia, "colliery" generally refers to an underground coal mine.

Lignite coal in Kosovo is and will continue to be an important local energy source due to its high reserves. Kosovo is very rich in lignite and accounts around 90% of Kosovo's electricity production. The nation has the 5th largest lignite reserves in the world and the 3rd in Europe. The lignite is distributed across the Kosovo, Dukagjin and Drenica Basins, although mining has so far been restricted to the Kosovo Basin. The lignite is of high quality for the generation of electricity and compares well with the lignite resources of neighbouring countries on a range of parameters. Kosovo's lignite varies in net calorific value from 6.28-9.21 MJ/kg, averaging 7.8 MJ/kg. The deposits can be up to 100 m thick, but average 40 m, and possess an average strip ratio of 1.7:1.
